--description--

As a reminder, this project is being built upon the following starter project on Replit, or cloned from GitHub.

equal() compares objects using ==.

--instructions--

Within tests/1_unit-tests.js under the test labelled #5 in the Equality suite, change each assert to either assert.equal or assert.notEqual to make the test pass (should evaluate to true). Do not alter the arguments passed to the asserts.

--hints--

All tests should pass.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
    (data) => {
      assert.equal(data.state, 'passed');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

You should choose the correct method for the first assertion - equal vs. notEqual.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
    (data) => {
      assert.equal(
        data.assertions[0].method,
        'equal',
        'Numbers are coerced into strings with == '
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

You should choose the correct method for the second assertion - equal vs. notEqual.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
    (data) => {
      assert.equal(
        data.assertions[1].method,
        'notEqual',
        ' == compares object references'
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

You should choose the correct method for the third assertion - equal vs. notEqual.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
    (data) => {
      assert.equal(
        data.assertions[2].method,
        'equal',
        "6 * '2' is 12 ! It should be equal to '12'"
      );
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );

You should choose the correct method for the fourth assertion - equal vs. notEqual.

(getUserInput) =>
  $.get(getUserInput('url') + '/_api/get-tests?type=unit&n=4').then(
    (data) => {
      assert.equal(data.assertions[3].method, 'notEqual', "6 + '2' is '62'...");
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
